Ethiopia trounces Somalia

The news reports of the Ethiopian military's rapid advance into Somalia, raises an obvious question. Quote:
I've just been talking with an FDD researcher who has been monitoring developments in Somalia via Arabic media. It does indeed appear that the Ethiopians are defeating Islamist forces there. Why are they achieving what American forces in Somalia in1993 did not and what American forces in Iraq today apparently are not?
Cliff May who asks the question, answers it: They're fighting to win.
